What are the barriers to ecash solutions such as
[cashu][1]
being developed on top of[monero][2]
?Lack of lightning network comes to mind. On the other hand, their blockchain fees are not high
despite dark market participants transacting on it extensively.

Cashu mints are a solution for the lack of privacy associated with the use of custodial lightning wallets. The LN itself attempts to solve the lack of privacy of onchain BTC, high fees for low value onchain transactions, and the high latency.
Monero attemps to improve its imperfect privacy if full chain membership proofs, rather than with L2 solutions. Due to its limited adoption the fees have not risen enough to be a problem. The problem of high latency of XMR remains unsolved.
There are no barriers, there is actually the reverse which is incentives, for example an open bounty and a developer did signal interest already

I suspect the dark market isn't huge compared to everything else
You can't build something good when the base is a pile of shit.
It will became more shit.
